Alright guys. I had a buying itch yesterday. I figured, I got such a good deal on my RS1's, why not add another set to the line up? But, I want to make it another set of cans that were distinctly another pair of cans.
Something different tonally, than the RS1. I'm planning on spending 4-500, and so far my thoughts are: Grado HF2 (yes, I know they're Grado, but tonally different than RS1), Denon AHD5000 (I've heard great stuff about this one, I'm only worried that the closed casing will limit soundstage), HD650 or Audio Technica AD2000.
My initial thoughts push me to the HF2, because I think it would be cool to own two Grados with two different sounds. I also like the Denon D5000 because I know both them, and the HF2 are fairly easy to push from an amp, which is also the same reason I'm swaying further from the HD650 and AD2000 because I'm still using my RA1 to drive my cans, because 90% of my usage is from my laptop while sitting on the couch, where there isn't much room for a larger amp.
